Optimize errstr() by reducing the number of times it walks a string.

As a side effect, it makes the code easier to read and requires less pointer arithmetic. Test by: strerror regression test Submitted by: Tim Kientzle

o Fix an English error (comma splice) and poorly worded sentence. o Fix KNF ordering of variables (pointers come before arithmetic types). o Restore hand-optimization of sizeof()-1, instead of strlen(). o Remove unneeded local variables in strerror_r().

strerror_r(). Doing this allows us to ensure that strerror_r() always fills the supplied buffer regardless of EINVAL or ERANGE errors. strerror()'s semantics have changed slightly such that an argument of 0 is now considered invalid and errno is set to EINVAL. Remove internal regression test for strerror() and strerror_r(). This will be reincarnated in src/tools/regression/lib/libc/string. In strerror(3), add a comment about strerror()'s bogus return type.

more careful about reporting truncation with ERANGE in strerror_r. Set errno to EINVAL for "unknown" errnum in strerror as required by P1003.1-200x Draft June 14, 2001. More carefully document the handling of strerrbuf when errors (ERANGE, EINVAL) are encountered in strerror_r. Reviewed by: bde (ongoing discussion)
